First, let me ask for some help....

SED participants, how do I answer a guy that just said this was
realistic to put on a five layer PCB?????

Do you ever purchase PCB's AT ALL!?!?!


All perspective I guess.
If you asked me how to break out this board, and suggested 5 layers I would assume you meant 5 ROUTING LAYERS or in other words an 8 layer board. 5 routing, 1 ground, 1 VCC, 1 Vcore. I find that some people refer to layers as only routing layers and ignore plane layers in the count. I never understood that logic but I often see it. Perhaps this is what they were saying.
